Researchers at Columbia University and The RAND Corporation recently completed a two-year study of over 1400 teenagers on the music they listen to, along with other factors such as peer pressure and parental supervision, and guess what? Turns out that—while "it was the old standbys of alcohol, drugs and peer pressure that typically led them into sexual encounters"—kids who delight in the bitches 'n' hoes talk of rap music are probably smacking dat a lot more regularly than their High School Musical-listening peers, with the results concluding that "adolescents who were exposed to the highest levels of sexually degrading lyrics were twice as likely to have had sex by the end of the study." As for how they decided on what was "degrading":

The researchers defined degrading lyrics as those that portrayed women as sexual objects, men as insatiable, and sex as inconsequential. One example they cited was from the rapper Ja Rule, whose song "Livin' It Up" includes the lyrics "Half the ho's hate me, half them love me." Notably, lyrics that celebrated sex, like those crooned by the band 98 Degrees — "I'm dreamin' day and night of making love" — had no effect on sexual behavior, the study found."

Really? Personally, I find it impossible to perform while listening to 98 Degrees.
